On solving the provided question, we can say that - so, percentage - 400/500 X 100 = 80%
What is percentage?A percentage in mathematics is a figure or ratio that is stated as a fraction of 100. The abbreviations "pct.," "pct," and "pc" are also occasionally used. It is frequently denoted using the percent symbol "%," though. The amount of percentages has no dimensions. With a denominator of 100, percentages are basically fractions. To show that a number is a percentage, place a percent symbol (%) next to it. For instance, if you correctly answer 75 out of 100 questions on a test (75/100), you receive a 75%. To compute percentages, divide the amount by the total and multiply the result by 100. The percentage is calculated using the formula (value/total) x 100%.
here,
total is 500
obtained is 400
so, percentage - 400/500 X 100 = 80%

I think the answer is 5.
Sorry if it's wrong.
Answer:
5
Step-by-step explanation:
This question is based on vector
By applying its formula
AC = AB + BC
we were given AC as 14 and BC as 9 so let find AB
AC = AB + BC
14 = AB + 9
AB = 14 – 9
AB = 5

Step-by-step explanation:
GIVEN :-
β ≠ 3γTO FIND :-
Value of xSOLTION :-
[tex]x - \frac{\beta x}{3\gamma} = \alpha[/tex]
Take 'x' common from L.H.S.
⇒ [tex]x ( 1 - \frac{\beta}{3\gamma} ) = \alpha[/tex]
Substract the terms in the brackets
⇒ [tex]x (\frac{3\gamma - \beta }{3\gamma} ) = \alpha[/tex]
Now , take the whole term in brackets to R.H.S.
⇒ [tex]x = \frac{\alpha }{\frac{3\gamma - \beta }{3\gamma} } = \alpha(\frac{3\gamma}{3\gamma - \beta}) = \frac{3 \alpha \gamma}{3\gamma - \beta }[/tex]
CONCLUSION :-
∴ [tex]x = \frac{3 \alpha \gamma}{3\gamma - \beta }[/tex] (Option E)

Function DefinitionA function connects various inputs together or produces a single output from each input. Simply explained, a function is a collection of equations that are linked to a single, identifiable output. A statement, rule, or law which explains the connection between two variables is known as a function in mathematics (the dependent variable). When a rule of this type is applied, there is just one output. by photographer Alex Federspiel.
Here,
=> (1−α)(1−β)(1+α)(1+β)
=>(1−α−β+αβ) /(1+α+β=αβ)
=> (1−(α+β)+αβ ) / ( 1+(α+β)+αβ)
=>(1 + 2/3 + 1/3 )/ (1 -2/3 + 1/3)
=> 2 x 3 /2 =3
=> (1−α)(1+β)+(1−β)(1+α) / (1+α+β+αβ)
=> 3(2−2αβ)/2
=>3(1−αβ)
=>3(1− 1/3 )
=>2
Therefore , the solution of the given problem of function comes out to be 2.

$34,100 at 4% for 3 years
Simple interest
The 3 year simple interest at 4% will be $38,192.
What is Simple interest?A quick and easy method of calculating the interest charge on a loan is called a Simple interest.
The principal amount = $34,100
Interest rate = 4%
Time = 3 years Now,
Since, We know that;
Where, A is final amount.
P is principal amount.
r is interest rate.
t is time.
Substitute all the values, we get;
A = $34,100 (1 + 4/100)³
A = $34,000 (104/100)³
A = $34,000 × 104/100 × 104/100 × 104/100
A = $38,192
Thus, The Simple interest will be $38,192.

Please!! What is the slope of each line?
Are they the same or different?
Given:
The graph of two lines.
To find:
The slope of each line and check whether they are same or different.
Solution:
If a line passes through two points, then the slope of a line is:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
From the graph 1, it is clear that the line passes through the points (2,175) and (3,165). So, the slope of first line is:
[tex]m_1=\dfrac{175-165}{3-2}[/tex]
[tex]m_1=\dfrac{10}{1}[/tex]
[tex]m_1=10[/tex]
The slope of first line is 10.
From the graph 2, it is clear that the line passes through the points (1,175) and (2,165). So, the slope of first line is:
[tex]m_2=\dfrac{175-165}{2-1}[/tex]
[tex]m_2=\dfrac{10}{1}[/tex]
[tex]m_2=10[/tex]
The slope of second line is 10.
[tex]m_1=m_2[/tex]
Therefore, the slopes of both lines are same, i.e. 10.

The surface area the sphere is 64π cm².
SphereA sphere is a three-dimensional equivalent of a two-dimensional circle. A sphere is a collection of points in three-dimensional space that are all the same distance r from a particular point. hat given point is the center of the sphere, and r is the sphere's radius
Surface area: 4πr²
How to determine the surface area of the sphere?Given the radius of the sphere is 4 cm.
then apply the formula
surface area = 4π(4)²

For the simple harmonic motion equation d=2 sin(pi/3 t), what is the frequency? If necessary, use the slash (/) to denote a fraction.
Answer:
The frequency is f = 1/T = 1/2 Hz.
Step-by-step explanation:
The frequency of a simple harmonic motion equation can be found by taking the inverse of the period. The period of a simple harmonic motion equation is the time it takes for the motion to repeat itself. In the equation d=2 sin(pi/3 t), the period is T = 2*(pi/3)/(pi/3) = 2 seconds. Therefore, the frequency is f = 1/T = 1/2 Hz.

Coach Soto bought a house at $350,000 that increases in value at a rate of 12%. Coach Torres bought a house at $275,000 and increased at a rate of 17%. Both coaches sold their house after 5 years, who made a higher profit?
Answer:
coach soto
Step-by-step explanation:
first figure out the profit, 350000 times 12% to get 42000. then multily 42000 by 5 wich is 210000 then add that to 350000 wich is 560000. then 275000 times 17% which is 46750 times 5, 233750 add that to 275000 which is 508750. so coach soto had a greater profit
